摘要
针对油田开发中、后期,层间矛盾突出,分层开采难度大的问题,提出了一种油井找水与选层开采一体化(IWISP)技术。对该技术的工作原理进行了分析,并给出了主要的技术指标。现场应用表明,该工艺技术设计合理,施工简单,提高了生产效率,不污染环境,经济效益可观,具有广阔的推广应用前景。
For the problem of oilfield development at the middle and late stages, obvious contradiction of zoning production is difficult, integrated technology of oil well water detection and select layer recovery is developed.By using switch controller, opening the docking claw, lifting cable, opening or closing the sleeve switch device of downhole string, random layer recovery and block off are achieved.This method achieves the purpose of going down the production string one-time after,non-stop production, fixing production string, completing water detection and water block off,it is designed reasonably for simple operation,and improving production efficiency without pollution,high economic benefits,it has wide application.
